In the UK, a full 5-year no-claims discount (NCD) typically reduces your premium by 50–65% — the single largest saving available to most drivers. It builds at one year per claim-free year; a single at-fault claim can wipe 2 years of discount. NCB protection costs 5–10% of your premium and allows one or two claims without losing your discount — but your base premium may still rise after a claim. Whether protection is worth buying depends on how much NCD you have and your assessment of your own risk.

What is the no-claims bonus?
The no-claims bonus (also called no-claims discount or NCD in the UK) is a reward insurers give drivers for each year they don't make a claim. It's the most powerful long-term discount in car insurance. The more claim-free years you accumulate, the larger the percentage reduction on your base premium. Most UK insurers offer NCD up to 5 or 9 years, with the steepest gains in the first five years.
In the US, the equivalent is typically called a good driver or accident-free discount. It's less formalised than the UK NCB system, but most insurers reduce premiums — usually 5–15% — for every three to five years without an at-fault claim.
In India, the no-claim bonus under IRDAI regulations is standardised: 20% after one claim-free year, rising to 50% after five consecutive claim-free years.
| Market | Year 1 | Year 2 | Year 3 | Year 4 | Year 5+ |
|---|---|---|---|---|---|
| UK (typical) | 30% | 40% | 50% | 55% | 60–65% |
| India (IRDAI-fixed) | 20% | 25% | 35% | 45% | 50% |
| US (approximate) | 5–10% | 5–15% | 10–20% | 10–20% | 15–25% |
What removes your no-claims bonus?
A single at-fault claim typically reduces your NCD by two years — so a 5-year NCD drops to a 3-year NCD, meaning you lose 10–15 percentage points of discount in the UK. Depending on your base premium, that could cost £150–£300/year extra until you rebuild it. The common mistake: people make small claims for minor dents and damage that cost less than the long-term NCD loss — then regret it.
Before making a claim for minor damage, calculate the cost of losing two years' NCD vs. the repair cost. If the repair is under £500–£800, paying yourself often preserves more value over the following three years.
What does NOT affect your NCB
- Claims where the other driver is entirely at fault and liability is fully established.
- Windscreen repairs (usually, if you have specific windscreen cover).
- Claims from named drivers on separate policies (in some, not all, insurers' terms).
NCB protection: is it worth buying?
NCB protection (sometimes called NCD protection) is an add-on that typically allows you to make one or two claims within a policy year without losing your no-claims discount. It usually costs 5–10% of your annual premium.
The maths: if you have a 5-year NCD on a £1,000 base premium, you're saving ~£620. Losing two years of NCD after a claim drops the saving to ~£500 — a difference of £120/year. If protection costs £50–£80/year and a claim would cost you £120/year for two to three years (£240–£360 total), the protection is probably worth it.
However: NCB protection does not protect your premium from rising after a claim. The insurer can — and usually does — raise the base rate at renewal following a claim, even if the NCD itself is preserved. NCB protection is not the same as premium protection.
Transferring your NCB when switching insurers
Your no-claims bonus is yours, not your insurer's. When you switch, your old insurer issues a no-claims certificate confirming your years of discount. Your new insurer accepts it and applies the equivalent discount. Do not cancel your old policy before getting this certificate — it can take several days to arrive.
